Turned on my TX-9500II the other day, lamps came on but no output.
Symptoms:
Unit is all original. Never been recapped.
No output with FM, AM, Rec Level Check regardless of any switch settings.
No meter movement.
No wide, narrow or stereo lights.
Checked the power supply voltages by checking pins of PA2002 on AWR-128:
1 = 26.4v ok
3 = 0.7v should be 3.4v
8 = 1.2v should be 4.2
10 = 0v should be 13v
Q1:
No shorts.
Collector = 26v ok
Base = 0v should be 13v
Emitter = 0v should be ?
AWR-128 pins 3,4,5 and 6 don't seem to be shorted to ground.
I intend to check C6, C8 and C12 then go from there. If they're ok, I'm thinkin' bad PA2002.
Feel free to chime in...
